Both 2 stroke? The Stihl almost certainly is, the mower maybe. If they are, yes they may use the same oil for premix though the oil/petrol ratio may be different. Stihl like the petroil to be really oily if you don't use their 2s oil.

If your mower is 4 stroke, no the 2 stroke premix oil for the chainsaw is different from the oil you put in a 4 stroke sump. Cheap multigrade from Halfrauds should do it.

If this question is a wind up, well done…..and use rapeseed oil in both, you'll be reet…. 😀

Chainsaw is either two stroke oil or chain oil. Dont use either of these as a lubricant oil in an engine as one is designed to burn and the other has anti fling qualities (yes really!)If its a Stihl use good quality Stihl stuff.

No it wasn't a wind up. I am a bumbling idiot. I do use Stihl engine and chain oils with my chainsaw. Its in my top 5 toys ever 8) I was wondering about the 2 & 4 stroke thing, that's why I was asking…will get some cheap Halfords stuff for the mower then. Ta

Are they the same? Can I put the engine oil I have for my Stihl chainsaw into my petrol push-along lawnmower?

I went to my local garden centre to get some oil but they don't sell lawnmowers anymore! Nor the oil you need for them. Takes up too much space which can be put to better use selling fluffy toys, pot pourri and jars of glass pebbles. 👿

Just checking my works mower and I need sae 30 and not 10-30 as I mentioned.SAE 10-30 will run thinner so you will use more and the engine will run hotter.
Google the make of engine,as alot of mowers use the same engine(honda or Briggs and Stratton for example)
Hope that helps
